SWITCH FOR BULL-PASSES.

Application filed September 6, 1918.

To ul whom it'ma concern:

Be it known that l, THoMAs D. House, a citizen of the United States, residing at Duluth, in the county of St. Louis and'State of Minnesota, have invented certain new and useful Improvements in Switches for Roll-Passes, of which the following is a specificationQ This invention relates to the metal rolling art, and more particularly to a switch for roll passes.

- One object of this invention is to facilitate directing metal being rolled into the proper roll passes.

Another object is to provide a simple and eilieient switch for roll passes adapted to meet the various requirements for successful commercial use.

These and other objects are accomplished by means of'the arrangement disclosed on (the accompanying sheet of drawings, in which- Figure 1 is a fragmentary plan view of a rolling mill showing my switch mechanism arranged adjacent an associated roll; and,

Fig. 2 is a sectional view taken in the plane of line 2-2 of Fig. 1.

Referring to the figures of the drawings, it will be noted that I have shown an apron 10 arranged adjacent a pair of rolls 11, only one of which is shown, provided with a plurality of passes 12 varying in dimensions, whereby metal run through said passes will receive corresponding shapes. The metal, which it will be understood is in a workable condition, is passed over the apron 10 toward the rolls 11 by driven rolls 13, only. one of which is shown adjacent the apron.

It is necessary that the metal be directed into various ones of the passes 12 of the rolls 11 for shaping the metal, the metal being directed either manually or automatically. The metal is first directed through the large passes and then later through the small roll passes. To improve the control mechanism for directing" the metal into the various passes. I have provided a novel switch mechanism including three pivotally mounted members 14, 15 and 16 pivotally connected to each other by a single pivot pin 17 which extends through the apron 10. This pivot pin i7 may occupy one of a plurality of openings 18 in the apron 10 whereby the switch he adiusted laterally. Each of the switch members 15 and lid is Specification of Letters Patent.

Serial No. 252,859.

the reception of a hooked clamp 20, the lower hook portion of which embraces a clamping bar 21 extending transversely of the apron 10 in advance thereof. The upper ends of the hooked clamps are threaded and provided with cooperating nuts 22, whereby the members 1 1 and 15 may be clamped or loosened, whereupon they in y be adjusted laterally independently of each other and with respect to the apron for directing the metal into the various roll passes 12. The switch member 16 controls the passage of the metal to one side or the other of the switch members 14 and 15.

As shown in Fig. 1 of the drawings, metal which is being fed toward the grooved rolls will he directed past the switch member 15 because of the fact that the switch member 16 has its free end in engagement with the side guard 23 at a point over the feed rolls 13. If it is desired to direct the metal past the switch member 14, the same is accomplished by drawing the switch member 16 over to the opposite side guard 23, said switch member 16 being controlled in its movement by any suitable operating handle 24. Associated with the diverging switch members 14 and 15 are side bars 25 and 26, respectively, which may be secured to the apron side rails in any suitable man, ner, it beingunderstood that these side bars may be adjusted in a swinging movement in accordance with demand by loosening nuts 27'.

By means of this switch mechanism metal may be directed toward various passes in the grooved rolls 11 in a simple and eliicient manner, the switch members being adjustable with respect to each other and with respect to the stationary feed apron to meet all of the requirements.

It is my intention to cover all modifications of the invention falling within the spirit and scope of the following claims.

at I claim is: t

.1. A switch for roll passes including; three pivotally mounted members connected to each other at a common point and being adjustable for controlling the path of move ment of metal during a rolling: operation.

2. A switch for roll passes including a plurality of diverging members adjustable on a suitable support, and a pivotally mermaid switch member for directing metal Hit") past one or the other of said diverging members.

3. In combination, an apron, a switch for roll passes adjustably mounted thereon, said switch including diverging members "independently adjustable with respect to said switch including diverging members independently adjustable with respect to said apron and with respect to each other,

and a switch member pivotally connected to said diverging members for controlling the path ofmovement of metal past said diver ing members. a

5. n combination, an apron, and a roll pass switch adjustably mounted on said apron, said switch including three pivotally mounted members, two of which being adj ustable with respect to each other and with respect to the apron, the third switch memher being movable across said apron for directing metal past either of said two other switch members.

Signed at Duluth, Minnesota, this 31st day of August, 1918.
